JULIAN EARL MONTGOMERY, OF WHEELING, WEST VIRGINIA.

LUBRICANT-HEATING APPARATUS.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application filed May 21, 1918. Serial No. 235,911.

To all whom it may concern:

Be it known that I, JULIA; EARL MONT- GOMERY, a citizen of the UnitedStates of America, and resident of Wheehng, county of Ohio, and State ofWest Virginia, have ed for mounting in a convenient position upon aroll-housing of a sheet, tin or obbing mill whereby the heavy grease orother lubricant employed on the roll necks and bearings may bemaintained at a proper degree of fluidity for ready and economicalapplication.

A further object is to provide a greasepot and a hanger therefor whichare so constructed that they may be readily disposed in associatedrelation'upon a roll housing, and that the pot may be removed andreplaced with a minimum of inconvenience and loss of time.

.With these and other objects in View, the invention resides in thefeatures of construction, arrangement of parts and combinations ofelements which will hereinafter be fully described, reference being hadto the accompanying drawings, in which Figure 1 is a front elevation ofa roll housing, showing my invention applied thereto;

Fig. 2 is a side elevation of the same;

Fig. 3 isan enlarged view of the greasepot, partly in side elevation andpartly in section;

gig. 4 is a section on line 44.-, Fig. 3; an

Fig. 5 is a top plan view of said pot.

Referring to said drawings, in which like designating charactersdistinguish like parts throughout the several views 1 indicates anopen-top grease-container which is preferably of approximatelyrectangular form in top plan and which has a lateral encircling flange 2adjacent to its upper edge adapted for seating closely upon and to besuitably attached to a similar flange 3 located about the upper edge ofa casingwithin which the body of said container depends. The bodyportions of said container 1 and said casing L are relatively disposedto provide an intermediate contrainer-encircling space or chamber 5 intowhich steam is directed for impartin heat to the grease or othercontents of sai container.

To provide an increased surface area exposed to the heating influence ofsteam admitted to the steam chamber 5, thus increasing the efiiciency ofthe pot for grease-melting purposes, and, further, to provide for a morenearly uniform heating of the contents of the containerthat is, a moreeflectual heating of that portion of the contents which would otherwisebe remote from the container wallsthe said container has its bottomformed with a central flute-like crimp or fold 6 which stands elevated asuitable distance and which has its walls separated to provide a pocketor channel 7 that forms a part of, or communicates with, said steamchamber.

Projecting horizontally outward from each of the opposite ends of thecasing 4, and preferably constituting integral extensions of the flange3, are two supporting lugs 8 which are adapted to seat upon a pair ofhorizontally disposed parallel arms 9 composing parts of a hanger 10 bymeans of which is suspended the pot composed of the container 1 andcasing 4 hereinbefore described.

Said hanger 10 has a body of approximately inverted-U form adapted to bedetachably mounted upon the side of a roll housing 11, as by engagementof an integral eye-member 12 carried thereby with a hook or bolt 13rigidly carried by said housing. Said arms 9 constitute angularlydisposed extensions of the lateral members of said hanger body and areterminated at their outer ends by upturned terminals 14 Whereby chancedisplacement of the mounted pot is effectually prevented.

It will be noted that the position occupied by the pot, supported asaforesaid, is such with respect to the rolls to be lubricated thatapplication of the melted grease by means of the swabs usually employedmay be conveniently accomplished.

The casing 4 has flat-faced parallel transverse ribs 15 on its bottomadapted to seat upon the floor when the pot is lowered thereon, as whenthe container is to be filled, said ribs serving to support the pot inupright position.

Steam is conducted to the upper part of the steam chamber 5 through apipe 16 and is conducted from said chamber through a if pressure may bereleased from the chamber 7 What is claimed is 7 l.
